DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch and the wire harness in the park/
neutral position switch circuit.
The park/neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that engine can be started
only when the shift lever is in the P or N position
The park/neutral position switch sends a signal to the ECM according to the shift position (P, R, N or D).
The ECM determines that there is a problem with the switch or related parts if in receives more than 1
position signal simultaneously. The ECM will turn on the MIL and store the DTC.

Measure the resistance between terminal THO1 (THO) and body ground.
HINT:
If a circuit related to the ATF temperature sensor become open, P0713 is immediately set (in 0.5
second).
When P0713 is set, P0711 cannot be detected.
It is not necessary to inspect the circuit when P0711 is set.
(a) Disconnect the transmission wire connector from the
transaxle.
(b) Measure the resistance according to the value(s) in the
table below.
Standard resistance
HINT:
If the resistance is out of the specified range with either
the ATF temperature shown in the table below, the
driveability of the vehicle may decrease.
